Slow cooker Guinness beef stew with tender beef, hearty vegetables, and a dark, rich broth that handles dinner without needing a 27 page Power Point presentation.
Season the beef with ½ teaspoon of the salt and all of the black pepper.
Add the oil to the hot skillet. When it shimmers, add the beef in a single layer (work in batches if needed). Brown deeply on all sides, about 4–6 minutes per batch. Don’t rush this—color equals flavor.
Transfer the browned beef to the slow cooker.
Add the quartered onions, potatoes, carrots, celery, garlic, beef broth, Better Than Bouillon, Guinness, remaining ½ teaspoon salt, tomato paste, thyme, and sugar to the beef.
Stir gently to combine. Cover and cook on LOW for 7 hours, until the beef is tender.
Melt the butter and whisk in the flour to form a smooth paste.
Stir it into the stew.
Cover and cook for 1 more hour, or until the stew thickens slightly and coats the back of a spoon.
Remove thyme stems before serving. Taste and adjust seasoning if needed.
Notes
Storage:This stew keeps well, which is good news since it’s even better the next day. Store leftovers in an airtight container in the refrigerator and plan to enjoy them within a few days.It freezes without drama, too. Cool it completely, portion it out, and freeze for up to 3 months.Tips:
Brown the beef properly:This is where flavor starts. If someone tells you they don’t brown the beef and it’s “just as good,” they are lying.
Give it enough time: Tough cuts don’t respond to encouragement. Low and slow until the beef is tender, not when the clock says so.
Season at the end: Long cooking dulls salt. Taste and adjust right before serving so it eats like stew, not effort.
